Description
NK ATP2-420-120-SP – AC Current Transducer, ATP Series

- ATP series
- AC current transducer
- Full scale range = 100, 150, 200 A
- Output signal = 4-20 mA
- Power supply = 120 VAC/DC
- Case style = Split-Core
ATP Series AC Current Transducers sense currents from 0-200 A and provide a proportional analog VDC or mA output. Externally powered by 120 VAC/DC or 24 VAC/DC, the ATP Series AC Current Transducers eliminate the need for costly power supplies or voltage rectifiers inside the control panel. Designed for motor control applications with standard sinusoidal waveforms, these transducers feature user selectable input ranges, a choice of outputs and split-core or solid-core cases.

AC Current Transducer Applications
Commercial and Industrial Motor Control Centers
- 120 VAC/DC power supply option allows for powering off of readily available supplies; ideal for pumping, water/wastewater, boiler and other industrial applications.
- Eliminates the need for 24 VDC power supply or AC rectifiers within the control panel; saves space, material and labor associated with power supplies.
AC Current Transducer Features
Fast, Accurate RMS Measurement
- Unique ‘average responding’ algorithm provides RMS output on pure sine wave and constant speed loads, offering improved accuracy over two-piece solutions.
Jumper-selectable Input Ranges
- Each unit has multiple input range capability and can be used for a variety of applications, reducing the need for separate models.
Isolation Output
- Output is magnetically isolated from the input for enhanced safety and elimination of insertion losses.
Designed for UL/cUL and CE Approval
- Accepted worldwide.
AC Current Transducer Connections

Notes:
- Terminals are deadfront captive screw terminals.
- Use 12-22 AWG solid or stranded.
